Around 90 confirmed cases of the flu have been reported in Westmoreland County since the end of September.

Officials say a popular flu test is the rapid swab in which a nurse or doctor inserts a wire-like swab in a patient's nose and swabs the area. Then, in about 20 minutes patients receive the results for Influenza A and B.

"People prefer the test because it is such a turnaround for the results. Therefore a patient doesn't have to experience any type of blood draw where they might have to discomfort," said Kathleen Rosatti with Excela Health.

Rosatti said they've seen an increase in the number of patients with flu-like symptoms. She adds while it's highly recommended children, senior citizens and patients with underlying health problems get the flu vaccine every year, everyone should get the vaccine.

"The population that seems not to get the flu vaccine is young adults. They feel that this is something for the elderly or children, but we do see there are young individuals that do not feel this applies to them."
